Dexchlorpheniramine is used to treat symptoms of allergies, hay fever, and the common cold. It helps with runny nose, sneezing, itchy eyes, skin rashes, and hives. It can also manage skin irritation caused by allergic reactions.
Dexchlorpheniramine works by blocking histamine, a substance your body produces during an allergic reaction. This helps prevent allergy symptoms like itching, swelling, or sneezing.
For adults, the typical dose is 2 mg every 4 to 6 hours, not exceeding 12 mg per day. For children, the dose is usually 1 mg every 4 to 6 hours, based on their age and weight. Always follow your doctor's instructions.
Common side effects include drowsiness, dry mouth, dizziness, or constipation. Serious but rare side effects include difficulty breathing or severe allergic reactions. If you experience any unusual symptoms, report them to your doctor immediately.
People with glaucoma, severe high blood pressure, or urinary retention should avoid this medicine. It's not suitable for those allergic to antihistamines or for children under 2 years unless directed by a doctor. It's not recommended during breastfeeding or pregnancy without a doctor's advice. It may cause drowsiness, so avoid driving or operating machinery until you know how it affects you.
